2 Claims.

This invention relates to certain new and useful improvements in coin selectors and with regard more particularly to the inclusion of a simple arrangement for testing the weight of a coin or token deposited in the selector, and has for its principal object the provision of an improved construction of this character, which will be highly efiicient in use and economical in manufacture. i

Heretofore in the fleld of coin selectors, particularly a selector of the type used in .connection with vending machines and machines having mechanism, the operation of which is controlled by the deposit of a coin, many attempts have been made totest the weight of the coin or token deposited in the coin selector so that the selector would acceptcoins of a predetermined weight.

Many of these devices have proven to be unsatisfactory and costly in manufacture. When it is appreciated that coin selectors are'subjected to wear and undue usage in attempts to spurious coins therein, it becomes apparent that in order for a device of the character hereinafter described to be eflective for the purpose, it must comprise few parts, be positive deposit in its op-v or tokens only eratlon and economical in manufacture to the extent that it'not only can be manufactured cheaply but that it also can be assembled with a minimum of effort. It istherefore one of the principal'objects of this invention to provide in a coin selector a mechanism accomplishing these various objects.

. Other objects will appear hereinafter.

The invention consists'in the novel combination and arrangementof parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing showing the preferred form of construction, and in which:

Fig, 1 is a fragmentary view of a coin selector having embodied therein my improved coin weighing device;

Fig. 2 is a reverse view of the same;

Fig.3 is a top plan view taken substantially on line 3-3 of Fig. 1; a

Fig. 4 is a sectional detail view taken substantially on line l4 of Fig. l: i

Fig. 5 is a perspective view of the coin'weighmy invention; and

Fig. 6 is a sectional'detail view taken substantially on line 6-8 of Fig. 1.

The. present invention relates to coin selectors of the type shown in United States Letters Patents Nos. 2,292,472, dated August 11, 1942, and

2,310,596, dated February 9, i943, granted to myself and my co-inventor, Walter A. Tratsch. Reference to these two patents may be had for an understanding of the coin selector parts which I have not shown in the drawing of this application. I deem it not necessary to show the complete coin selector and therefore I have confined the drawing illustrations to such of the parts as cooperate with my coin weighing device as to render it understandable and operative.

'In this connection the coin selector is indicated generally at ID. This selector includes a plate II. This plate ll includes awall l2 and walls l3 and I3 extending substantially at right angles with respect to the wall i2. Spaced from the wall it and struck from the wall i2 is 9. laterally extending lug l4. Pivoted between this lug l4 and the wall l3 by means of pintles l5 projected through suitable openings l5 formed in the lug l4 and the wall 13', is a gate it. This gate l6 is normally retained in a closed position through the medium of a coil spring, I! mounted upon one of the pintles l5 as shown in Figs. 2 and 3. The lower end portion of the gate l6 provides an arm I8 the edge i9 of which provides arunway for a coin deposited through the coin entrance provided between the upper end portion of the gate l6 and the wall l2.

Secured to the wall i 2 is a plate 2| spaced from the wall 12 by a spacing block 22. Between this plate 2i and the wall I2 is a movable clean-o'ut bar 23. This clean-out bar 23 is pivotally carried by the wall l2 as at 24 and is normally held in the position shown in Fig. 2 by means of a coil spring 25, one end of which is connected to the plate l2 as at 25 and the opposite end to the bar 23 as at 21. This clean-out bar has formed thereon a lug 28 which projects through a slot-,2! formed in the wall l2. The ends of this slot 29 serve to limit the pivotal movement of the clean-out bar tegral part of the plate 33 and 22. For example, when the bar is in the position shown in Fig. 2, the lug 28 will engage the end 30 of the slot 29 and thus limit the upward pivotal movement of the clean-out bar 23. Likewise,

when pivoted in its lowermost position, this lug 28 will engage the lower end 30 of the slot 23 and thus limit the downward pivotal movement of the clean-out bar 23. This slot 29 is an ofiset to an arcuate slot 3| in which there is operative a finger 32 formed as an integral part of a plate 33.

This plate 33 is pivoted to the sidewall l2 as at 34 and is normally held in its uppermost pivotal position by means of a spring 35, one end of which engages a horizontal ledge 36 formed as an inthe opposite end bearing upon a stud pin 31. The plate 33 is adapted to have pressing engagement upon an angular Such coins may be caused to remain in the pas-' sage by virtue of magnetic attraction created by the magnetic elements 39 and Ml, the element 33 being carried by the wall l2 on one side thereof while directly opposite this magnetic element 33 the magnetic element 40 is carried by the plate 2|.

The coin selector thus far described is substantially similar in-structure to that disclosed in the two Letters Patents hereinbefore mentioned, to which reference may be had for a more detailed description of the operation and relationship of the parts thus described. It need here only be mentioned that acceptable coins which pass along the runway 19 are directed into-an acceptance passage A while spurious and other unacceptable coins are directed in the manner described in the patents aforesaid, into the rejection chute R.

My improved coin weighing device comprises a stud shaft ll. Mounted on this shaft ll is a sleeve 42. One end-of this sleeve 42 terminates into an enlarged disc-shaped head 43. Positioned to bear lightly against this head 43 is an arm 44. This arm 44 has one end 45 pivotally connected to the wall l2 as at 46. The arm 44 is normally held in. its pivoted position against the head 43 by means of a light spring 41 coiled about the pintle l8 of the arm 44, with one end connected as at 9 to the arm 44 and having its opposite end hearing as at 50 against the wall I2. The arm 44 is guided in its pivotal movement by means of a pin projected through an enlarged opening 52 formed in the arm H. The pin 51 is carried by the wall l2. The head 43 is disposed between the end 53 of the arm 44 and a light leaf spring 54' carried as at 55 by the arm 44.

The sleeve 42 is formed as an integral part of a cradle 56. This cradle 56 includes an angularly bent finger 51 which operates in a slot 58 (Figs. 1 and 4) formed in the plate I2. -A second angularly bent finger 59 is provided by the cradle in spaced relation to the finger 51, and this finger 59 operates in a slot 60 (Fig. 1) formed in the plate I2. To complete the cradle, there is provided a counterweight 6| which normally holds the cradle-in the position shown in Fig. 1 and which counterweight nicely balances the cradle so that it will be pivoted only in an anticlockwise direction by a coin of proper weight. These fingers 59 and 51 extend into the entrance 20 in the path of movement of coins into and through this coin entrance 20. A coin of proper weight will lodge upon each of the fingers 51 and 59 and as the linger 59 is offset considerably with referenceto the axis of rotation of the cradle, thecoin, being of proper weight or a weight suflicient to, overcome the action of the counterweight 6|, will pivot the cradle at the end of the rotation of the cradle the coin will be free to drop upon the runway IQ for passage through the acceptance passage A and thence into a coin collector box (not shown).

On the other hand, should the coin not be of proper weight or a weight sumcient to pivot the cradle in an anticlockwise direction, as viewed that a simple arrangement inFig. l,theninsuchcase,whentheplate33is pivoted downwardly, a lug 83 carried thereby will bear against the inside surface of the arm 43, pivot the same away from the plate in a direction to slide the sleeve 42 on the stud shaft ll to retract the fingers 51 and 39, and thus permit the spurious or unaccepted coin to drop by gravity into the rejection chute, and thence to a. return chute (not shown).

From the foregoing description it is apparent of parts is provided for testing the weight of the ooin'or other tokens deposited in the coin selector, and that only coins or tokens of the proper weight willbe permitted to pass into the acceptance passage.

While I have illustrated and described the preferred form of construction for carrying my invention into eifect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims. c

Having thus described my invention, what I I claim as new and desire to protect by Letters Patent is: r

1. A coin selector comprising a wall, a gate carried by the wall and movable toward and away from the wall and providing with the wall, when 7 having aporin one position, a coin pasage and tion providing a coin runway on which coins of a predetermined weight are supported for movement down said runway, means for pivotally moving the gate in a direction away from the wall, coin weighing means having portions extending into said passage and adapted to be pivoted by the weight of a coin thereon of a predetermined weight to permit said coin to pass through said passage onto said runway, means in an anticlockwise direction and providing pivotal connection between the wall and the coin weighing means, means actuated by movement of the gate pivoting means for moving said coin weighing means in a. direction to dispose said portions thereof from position in said passage, means providing an acceptance passage for coins gravitating down said runway, and means providing a rejection exit commimieating with said coin passage and adapted to receive coins from said passage when said gate is moved away from said wall.

2. A coin selector comprising .a wall, a gate carried by the wall and movable toward and away from the wall and providing with the wall when in one position a coin passage and having coins therefrom, means providing'a rejection exit a and communicating with'said coin passage, and
